Description
editThe lichen lacks a thallus and can be found on the bark of Eastern White Cedar. Apothecia are singular or in groups of 2–7, black or greenish, and epruinose.[2] Apothecia range from 0.14–0.28 mm tall, and 0.11–0.30 mm across, and have an absent or extremely short stock, 0.02–0.08 mm in diameter; they are visible with a 20X hand lens.[2] Asci are cylindrical, 34–50 μm long and 2.5–4.5 μm wide.[2] Ascospores are septate, pale brown, ellipsoidal, 6.0–10.5 μm long and 2.0–3.0 μm wide.[2]
Habitat
editChaenothecopsis jordaniana is found only in Minnesota. Most commonly located on the bark of the Eastern White Cedar in narrow ridges.[2] The majority of trees it is found on have weathered white and grayish bark. Apothecia are found where grayish bark transitions to a brown hue, similar to younger tree bark.[2]
Etymology
editChaenothecopsis jordaniana is named after Dr. Peter Albion Jordan (1930–2017).[2]
